What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It’s easy for humans to read and write, and easy for machines to parse and generate. Developers use JSON to send data between servers and web applications, store configuration, and much more.

Formatting JSON makes it readable by adding indentation and line breaks – essential for debugging and understanding complex data structures.
